WORLDKINGS - Worldkings News - Europe Records Institute (EURI) GFRP Lleida Pedestrian Bridge: World’s longest arch bridge made out of standard GFRP pultruded profiles

20-09-2022

(WorldKings.org) FRP Pedestrian Bridge is a tied-arch 38 meters long and rises 6.2 meters.

The FRP Pedestrian Bridge or Passarel·la de la Ciutat Jardí in Lleida, Spain is the longest arch bridge made out of standard GFRP pultruded profiles.

Fibre-reinforced plastic (FRP; also called fibre-reinforced polymer, or in American English fiber) is a composite material made of a polymer matrix reinforced with fibres. The fibres are usually glass (in fibreglass), carbon (in carbon-fibre-reinforced polymer), aramid, or basalt. Rarely, other fibres such as paper, wood, or asbestos have been used. The polymer is usually an epoxy, vinyl ester, or polyester thermosetting plastic, though phenol formaldehyde resins are still in use.

The bridge spanning the Madrid-Barcelona high-speed rail link won the international “Footbridge Award 2005” in the category “Technology” for medium span (30m-75m) bridges.

The structure is a tied-arch 38 meters (125 ft) long and rises 6.2 meters (20 ft). The deck is 3 metres (9.8 ft) wide. The bridge is entirely made out of GFRP pultruded profiles. The arch configuration was chosen so as to minimize serviceability problems due to the low modulus of elasticity of GFRP profiles. The choice of GFRP was influenced by the fact that the material is an electrical insulator and eliminates magnetic interference with the electrified railway.

The glass fibre reinforced plastic beams and panels used in the footbridge were manufactured in Denmark and assembled in Spain.

It was successfully installed in October 2001. The bridge was fabricated in only three months and erected by crane in just three hours.
